Why is the Pt1000 temperature sensor predominantly chosen for heat measurement? What are the dist...
Pt1000 is a platinum thermal resistor whose resistance value varies with temperature. The “1000″ after “Pt” means it has a resistance of 1000 ohms at 0°C and approximately 1758.56 ohms at 200°C. The resistance of PT1000 increases steadily as the temperature rises. Pt100 is...Read more -
What are the measuring range and the turndown ratio?
What are the measuring range and the turndown ratio? The measuring range is the value of the difference between the upper and lower limits of the nominal range of an instrument. If the lower limit of measurement of an instrument is zero, then the maximum value of the physical quantity that can be...Read more -
The conversion formula between the flow velocity in a pipeline and the flow rate:
The conversion formula between the flow velocity in a pipeline and the flow rate: The flow rate is equal to the cross-sectional area of the pipeline multiplied by the flow velocity of the fluid. Let the flow rate be Q, the inner diameter of the pipeline be D, and the flow velocity of the fluid be...Read more -
